  By the way, in the shutter device shown in the above-mentioned patent documents 1 and 2, when the shutter curtain is closed, there is an obstacle in the closing movement direction of the shutter curtain, and the screen comes into contact with the obstacle. The impact received by the obstacle due to the slack of the screen is small. However, the slack portion of the screen may be sandwiched between the upper end surface of the prism member that is the stop portion and the lower end portion of the slat connecting body. In this case, the obstacle is removed. However, the screen will remain loose. That is, the screen remains in a semi-open state.

  For this reason, even if the closing screen is in contact with an obstacle, the obstacle is removed, so that the screen can be closed and moved until it reaches the fully closed position or the substantially fully closed position more reliably. The device was devised.

  The object of the present invention is to move the closing body until the opening / closing body reaches the fully-closed position or the substantially fully-closed position more reliably by removing the obstacle even if the closing-opening opening / closing body contacts the obstacle. An object of the present invention is to provide an opening / closing device that can be used.

As shown, the step portion 41 can stay while slackening.

  As a result, as shown in FIG. 9, the slack portion 20E of the screen 20 is formed between the lower surface portion 15C of the cover member 15 which is the lower end portion of the slat connecting body 13 and the upper surface portion 35A of the columnar member 35. It is prevented from being caught between them.

  9 shows a state immediately before the lower surface portion 15C of the cover member 15 that is the lower end portion of the slat connecting body 13 is placed on the upper surface portion 35A of the columnar member 35 that is the stop portion, that is, the shutter curtain 11 is entirely FIG. 10 is a diagram showing a state immediately before reaching the closed position or the substantially fully closed position. From the state of FIG. 9, the shutter curtain 11 is further extended from the winding shaft 10, and the lower surface portion 15 </ b> C of the cover member 15 is the columnar member 35. The slack portion 20E of the screen 20 stays at the stepped portion 41 until it is placed on the upper surface portion 35A of the screen, so that the slack portion 20E is formed between the bottom surface portion 15C of the cover member 15 and the columnar member 35. It is prevented from being sandwiched between the upper surface portion 35A.

  Thereafter, when the obstacle 110 shown in FIG. 9 is removed, the screen 20 having the slack portion is caused by the weight of the screen 20 and the weight of the flat bar 22 arranged inside the bag portion 21. As it closes and moves, the slack portion 20E staying in the step portion 41 is stretched. Thereby, the screen 20 reaches the fully closed position or the substantially fully closed position as in the case where the obstacle 110 does not exist in the closing movement direction of the shutter curtain 11.

  Therefore, as described above, according to the present embodiment, even if the screen 20 of the shutter curtain 11 that is in the closing movement contacts the obstacle, the obstacle is removed, so that the screen 20 is more reliably It moves to close until it reaches a closed position or a substantially fully closed position.
